I used to use the keyboard a lot in Opera back in the day. Favorites included searching for links on the page by text and pressing enter to get there, and navigating back/forward using "link rel" tags in the documen (for example, you could go to the "next page" regardless of the browser history)

I seem to recall that web pages were steadily making it harder for it to work. E.g no "a href" or "link rel"s.

Here's hoping that Nyxt will have success in bringing this era back!
